Java doesn't have the ability to print in a "text" mode.  The graphic 
mode is more complicated but it follows GUI creation and drawing very 
closely.

If you have a printer attached directly to your computer you could try 
this code;

import java.io.*;

public class test {
     public static void main(String[] args) throws Exception {
         FileOutputStream fos = new FileOutputStream("LPT1:");
         PrintWriter pw = new PrintWriter(fos);
         for (int i=0; i<50; i++)
             pw.println(i);
         pw.close();
     }
}

It's not going to work for network attached printers unless you can get 
a OS character device for them.
